A Detailed Guide to the Latest Planting Methods and Cultivation Techniques for Solomon's Seal (Polygonatum odoratum)
Solomon's seal (Polygonatum odoratum) is a herbaceous plant of the lily family, with a very widespread wild distribution in China. It is also a traditional Chinese medicinal herb with a relatively long history of use in China; the main medicinal part is the rhizome, which has effects such as nourishing yin and moistening dryness, and clearing heat to relieve cough. It has a relatively good effect on lowering blood sugar and blood lipids. So how should Solomon's seal be planted? Below, the editor brings you the planting methods for Solomon's seal, let's take a look!
1. Site selection and land preparation
The wild area of Solomon's seal is very large, so its adaptability to soil is also relatively strong. However, when artificially cultivated, the main focus is on yield, so before planting we still need to do a good job of soil selection. The planting soil for Solomon's seal must be guaranteed to be thick, loose and soft, with normal drainage and irrigation and sufficient light, and the soil nature should be slightly acidic and sandy. After selecting the soil, carry out land preparation, turning the soil deep by about 30cm. Then apply sufficient organic fertilizer per mu as the main base fertilizer, with the amount controlled at about 3500kg. After fertilizing, break up the soil finely, rake it level, and make high beds.
2. Selection of seed stems
The propagation method of Solomon's seal is generally mainly by seed stems, so before propagation we must select good underground rhizomes as seed stems. The selection of seed stems should be judged based on aspects such as the size and color of the rhizomes. Generally, during the autumn harvest, select the plump, light-yellow root buds of the current year for use as rhizome propagation. The propagation of Solomon's seal should follow the principle of planting immediately after digging; if the weather is really unsuitable for planting, then the root buds should be stored in a cool indoor place to prevent deterioration and rot that would reduce the germination rate. Finally, the amount of seed stems per mu should be controlled at about 250kg.
3. Sprouting of seed stems
Before planting, the seed stems also need to undergo sprouting work. First, soak the seed stems in cold water for one day, then take them out and air-dry the water. Place the seed stems in wet sand and put them into a container; the bottom of the container should first be covered with about 4 centimeters of wet sand, and after loading, cover the top with about 5 centimeters of wet sand. The water content of the sand should be controlled at about 15%, then place it at a temperature of about 25 degrees. Check the changes in temperature and humidity every three days, and adjust the humidity appropriately. Check the sprouting situation after about 10 days; when a large number of seeds appear in the seed embryo of the seed stems, then place them at a temperature of about 5 degrees for one month, carrying out three rounds of turning the seeds, and after one month they can be sown.
4. Planting at the right time
The planting time for Solomon's seal is generally in October each year. When planting, pay attention to the weather; do not plant on rainy days. Planting should be done on cloudy or sunny days, and when planting, first do a good job of digging furrows. Control the row spacing on the bed surface, keeping it at about 30 centimeters, and dig furrows about 15 centimeters deep. Then place the seeds neatly and flatly in the furrows; after placing them, spread a layer of decomposed farmyard manure on top, then cover with fine soil, water, and wait for germination.
The above is a brief introduction to the planting methods for Solomon's seal. The planting methods for Solomon's seal are actually relatively simple, but management must also be strengthened to increase yield. That is all for today's introduction; this article is for reference only, and I hope it can be of some help to everyone.
